Problem & answerN-08
Uneven Flow Between Vibratory Trays
Also covers: Product piling at tray junctions or gaps in flow
Likely causes
- Vibration settings not tuned for the product (each tray needs its own value)
- Vibrator start delays incorrect
- A tray set too slow for the product arriving from the tray before it
- Product sticky (gummies) or damp
How to fix it
- 1Watch the flow across tray 1 to tray 2 to tray 3.
- 2On the counter PLC, adjust each vibrator separately until pieces spread out into single file with no piling at the tray junctions. Vibrator 3 usually runs highest (reference values in Section 4.2).
- 3Check vibrator 1 and 2 delays (reference 3 s).
- 4Balance left and right lanes so both feed evenly.
- 5Check product condition and room conditions for gummies.
- 6Record the final settings for the product.
